Electric Actuated Butterfly Valve - DynaFly Series - 700/722 Series - DynaQuip Controls
St. Clair, MO, United States
Electric Actuated Butterfly Valve DynaFly Series - 700/722 Series
The DynaFly 70 Wafer and 72 Lug Series are the work horses of industrial butterfly valves. Pre-sized and preassembled with our MA series electric actuators, these valves come standard with ductile iron body and disc and abrasion-resistant Buna-N Phenolic Backed Seat for stretch resistant, tight shut-off during actuation and quick and easy field repairs. Other voltages and body or seat materials are available on request. Please select Search by Specification to narrow product results for a specific application. 70/72 Series Specifications and Options: Wafer Style (700) or Lug Style (722) Bodies Standard Body Material: ASTM A536 Ductile Iron Standard Disc Material: Ni-Coated Ductile Iron Also Available: Aluminum Bronze and 316 Stainless Steel Standard Seat Material: Buna-N Also Available: EPDM, TFE, Viton® 200 PSI CWP 2-12" direct mount, 175 PSI CWP 14-24" bracket mount Temperature range: -40 deg F to 350 deg F (Dependent on seat material) Operator: MA series Electric Actuator (DynaFly Series) Key Actuator Specifications and Benefits NEMA 4 Weatherproof/Corrosi on resistant housing Manual Override and Non-clutch side mounted hand-wheel Die Cast Aluminum with Epoxy polyurethane paint Two (2) 1/2" NPT conduit entries Self-locking, high allow steel gear train Reversing Motors, Thermal Overload Protection, 30% Duty rated long life Four (4) Limit switches for Motor Control and Remote Indication of End of Travel Adjustable mechanical travel stops and Local visual position indication 120 V ac, single phase standard. Additional voltages available including: 12 V dc, 24 V dc, 24 V ac, 220 V ac single phase, 230 V ac triple phase, 460 V ac triple phase Key Valve Specifications and Benefits NEMA 4 Housing with Manual Override and Handle-Wheel Self-locking gear train and reversing motor Multiple Voltages Available Support Shaft Seal: A bonding of elastomer to phenolic backing ring protects against distortion, a common cause of shaft leakage Wide flange-face sealing area provides a tight flange-to-valve seal and negates the need for flange gaskets Once-piece 416 Stainless Steel stem shaft ensured dependability and positive disc positioning Locating holes at bottom and top of Wafer Valve Ease Installation. Lug style valve has drilled and tapped lugs meeting ANSI 125/150 flange standards Precision Profile Disc provides bubble-tight shut-off and assures minimum torque and longer seat life Set Screw stabilizes the seat to prevent movement. Positive dead-end service up to 75PSIG MAX Precision Taper Pin Ensures a positive vibration proof shaft to disc connection Once-piece 416 Stainless Steel stem shaft ensured dependability and positive disc positioning Four Bushings furnish shaft support for positive shaft alignment and actuator support
